我正在使用flask-admin构建产品admin。产品可以具有单个或多个变体集。例如，一件T恤可以设置“大小”设置，其中包含S，M，L的记录。夹克可以同时设置“大小”和“颜色”（红色，绿色，黄色等）设置。
理想我希望管理员能够从产品视图中删除所有产品变体。产品视图上的所有其他字段只是该模型的常规flask-admin默认字段。草图示例：
我是flask-admin的新手，所以在开始hackjobbing之前，是否存在以前在flask-admin驱动的UI中建立这种关系的先前路径？我在考虑某个字段替代，以在页面内还是在模式窗口中加载自定义窗口小部件（或其他模型视图）？
下面是我对flask-sqlalchemy采取的方法的简化概述。
